It blooms between August and November producing simple inflorescences that occur in groups of 6 to 16 on the raceme with the spherical flower-heads contain 17 to 20 creamy white coloured flowers. The thinly coriaceous glabrous seed pods that form after flowering have a narrowly oblong shape and have a length of up to 14 cm and a width of 9 to 11 mm. The seeds within have an oblong to ovate-elliptic shape with a length of 4 to 5 mm and a thick black aril.

Taxonomy
The specific epithet honours Mabel Fanny Cambage who was the daughter of R.H. Cambage, a colleague of Joseph Maiden. It is also sometimes referred to as 'mabelliae', but this spelling change is not correct.

Distribution
It is native to an area of New South Wales on the coastal slopes of the Great Dividing Range from around Camden in the north down to around Bermagui in the south growing in gullies in sandy soils as a part of open Eucalyptus woodland communities.
